RAIL ANTIGBEEPER.

Application filed May 29, 1925, Serial No. 33,638.

The object of the present invention is to provide a new and improvedanti-creeping device constructed to grip the rail, and which when usedin the ordinary manner of rail-anchors abuts against a tie so that thelongitudinal movements of the rail in one direction are transmitted tothe tie, and which when used vith a suitably constructed tie-platetransmits to the tie the longitudinal mov ments of the rail in bothdirections caused by reversal of traiiic or by the expansion andcontraction of the rail or by its reaction from the wave movement ofone-way trafiic.

In the accompanying drawings Fig. 1 is a top plan view of a deviceembodying my invention assembled in place on a rail and against a tie;Fig. 2 is a View partly in side elevation and partly in section on theline 2-2 in Fig. 1; Fig. 3 is a view showing one end of the device inplace on a rail with a portion of a tie in section; Fig. 4 is a detailview on the line &i in Fig. 2; Fig. 5 is a view similar to Fig. 1showing the device as sembled in position with a form of railwaytie-plate with which it may be used; Fig. 6 is a view partly in sideelevation and partly in section on the line 66 in Fig. 5, and Fig. 7 isa view showing one end of the device in place on a rail with part of thetie-plate and with a portion of the tie in section.

In the drawings the reference letter A designates the head of a rail, Bits base and 0 its web, and D is an ordinary wooden tie.

The anchor consists of a rectangular metallic plate having a flat baseor body 1 which is provided at one end with an overhanging lip 2 and atthe other end with a rail-abutting shoulder 3 which is preferablyrounded off or slightly beveled at its upper inner edge. The dimensionsof the anchorplate are such that when assembled upon a rail-base oneedge of the latter fits under the lip 2 and the other edge abuts againstthe shoulder 3, the rounded or beveled upper edge of the shoulderpermitting the rail-base to pass down to place. The anchor-plate isprovided with a longitudinal central slit 4 which passes through its lip2 so that the two wings thereby formed may be spread laterally apartwhen a suitable wedge 5 is driven to place between them, and the twojaws formed by the split lip may be spread apart to engage therail-base. The end of the plate carrying the lip is extended so as toform a seat for the wedge well within the Renewed June 1, 192?.

area of the body of the plate itself. When the anchor-plate is assembledupon a rail base and the wedge is driven into its seat the lateraljar-5s formed by the split lip are spread apart so that the outer edgesof their undercut portions bind on or bite into the edge of therail-base as shown clearly in Fig. 4, and the outer under corner of eachportion of the jaw binds or bites into the upper beveled face of therail-base as shown in Figs. 2 and 6. By thisconstruction theengagementof the lip 2 with the rail-base holds the shoulder 3 in engagement withthe other edge of the rail-base, so that the an-- ehor-plate firmlygrips the rail. In practice the anchor-plates are assembled upon therails in position to abut against the ties, so that the longitudinalmovements of the rail in one direction are transmitted to the ties.which resist the same as they are embedded in the ballast. In practice Iprefer to form the anchor-plate with a depending wing 6 on the sidewhich abuts against the tie in order that the vertical motion of therail due to its wave-like movement under traffic may not raise theanchor-plate above the line of. the upper surface of the tie. Theanchor-plate is assembled on the rail-base by passing it beneath thebase and hooking its lip 2 onto one edge thereof, when the opposite endis moved up until the corresponding edge of the base seats against theshoulder 3, and the wedge 5 is then driven to place in its seat.

In the form shown in Figs. 5, 6 and 7 the anchor-plate is combined witha suitable tie-plate to form a two-way anti-creeper. The tie-plate E isformed of metal and is of sufficient size to provide a suitable seatingsurface for the rail-base and to have one of its sides extend beyond theside of the tie as shown for example in Fig. 5 when the plate is spikedthereto in track as at e. The extended or overhanging end of thetie-plate is provided with a transverse recess E which is long enough toreadily admit the anchor-plate into position therein; these dimensionsmay be so related as to allow the anchor-plate sufficient endwise playin the recess to assemble and disassemble it in position on therail-base while the latter is spiked to the tie as shown in Fig. 2, orthey may be so related that the anchor-plate after being assembled onthe rail-base can be dropped into the recess when the rail is placed onthe tie-plate with its ends abutting the ends of the recess as indicatedin Fig.

6 to enable the anchor-plate to resist side thrusts of the rail. Therecess in the tieplate is of sufficient width to receive theanchor-plate in assembled position therein and to fit against the outerends of the jaws of the anchor-plate when the latter are spread by theirwedge as shown in Fi 5; these dimensions preferably are such that thesides of the anchor-plate will fit snugly against the side walls of therecess to enable the anchor-plate to abut against the tieplate in eitherdirection without undue lost motion or play. In this use of the anchorplate I prefer to form it with opposite depending marginal wings 6 asclearly shown in Fig. 7', so that the sides of the anchor plate will notrise out ofthe recess of the tie-plate under the vertical action of therails due to their wave-like motion from passing traflic. Theanchor-plate grips the rail and snugly fits the sides of the recessin:the tie-plate, so that the anchor'plate will transmit all longitudinalmovements which the rail may have in either direction to the tie-plate,and as the tie-plate is spiked to the tie the latter resistslongitudinal movement of the rail in both directions: By thisorganization a railanchorage is provided which resists rail creeping inboth directions as it interlocks the rail and tie so that all movementsof the former are transmitted'to the latter.

Inboth uses of the anchor-plates the clepending side wings abut againstthe sides of the ties to transmit the lengthwise stresses of the raildirectly against them.

I claim:

I. A rail anti-creepercomprising a base having a rail shoulder at oneend and an overhanging lip at its other end, the base being' providedwith alongitudinal slit extendin'g throughsaid lip to form oppositelateral jaws, and a wedge to spread the jaws.

2'. A rail anti-creeper comprising a base having a rail shoulder at oneend and an overhanging hp at its other end, the base having a dependingside wing and being provided with a longitudinal slit extending throughsaid lip to form opposite lateral jaws, and a Wedge to spreadthe jaws.

3. A rail anti-creeper consisting of a tieplate constructed with anextension projecting beyond one side 01' the associated tie and having arecess transverse to the length of a railbase and longer than the widthof said base, and an anchor-plate extending across the underside of therailbase and fitting within said recess, said anchor-plate havingrail-engaging members adjacent its ends and having a longitudinal slitextending through one end and dividing the associated railengagingmember into sections, and a wedge to spread said sections.

4r- A rail anti-creeper cons sting of a tieplate constructed withextension projecting beyond one side of the associated tie and having arecess transverse to the length ot a rail-base and longer than the widthof said base, and an anchor-plate fitting within said recess andextending across the underside of the rail-base and having a shoulder atone end and an overhanging lip at its other end, said anchor-platehaving 21 depending side wing and a longitudinal slit extending throughsaid lip to form lateral jaws, and a wedge to spread the jaws.

5. A rail anti-creeper consisting of a tieplate constructed with anextension projecting beyond one side of the associated tie and having arecess transverse to the length of a rail-base and longer than the widthof said base, and an anchor-plate fitting within said recess andextending across the underside of the rail-base and having a shoulder atone end and an overhanging lip at its other end, said anchor-platehaving depending side wings and a longitudinal slit extending throughsaid lip to form lateral jaws, and a wedge to spread the jaws.

In testimony whereof I hereto aiiix my signature.
